A wise man would always use a fused DC power lead, not just for initial testing but also for normal operation. If you ever develope a DC power short, such as a shorted D19 (zener across the final PA) due to transmitting without an appropriate antenna, you'll wish you had that fuse.

A temperature controlled iron is an optional luxury item. I've never used one in more than fourty years of soldering projects. Presumably there would be instructions included with the unit.

It doesn't seem reasonable to require a kit manufacturer to provide all this basic "skill of the craft" type training. I know Heathkit never did, nor do any other ham kit manufacturers of whom I am aware. When training of this nature is required, most get it in person from a kindly and helpful "Elmer."
I don't recall finding any problems with the manual I used for my old K1 SN 175. I do think it's past time for the current K1 manual, last revised 2.5 years ago, to be revised to correct the order of steps for installing a jumper at RF-RFC8 prior to doing voltage tests. Some people seem to miss Errata Sheet instructions.
